The error message "Prelaunch task build terminated with exit code 1" typically indicates that there was an issue with the prelaunch task specified in your Visual Studio Code configuration. The exit code 1 generally means that the prelaunch task failed to execute successfully.

Here are some steps you can take to troubleshoot and resolve this issue:

  1. Check Task Configuration:
    Open your Visual Studio Code project's .vscode/tasks.json file and review the prelaunch task configuration. Ensure that the task is correctly defined, and there are no typos or errors in the configuration.

  2. Verify Build Command:
    If your prelaunch task is intended to build your project, ensure that the build command is correctly specified. Check that the paths, arguments, and options are accurate.

  3. Check Build Output:
    If your prelaunch task is supposed to build your project, it's a good idea to execute the build command from the terminal directly. This will allow you to see the detailed build output and any error messages that might be generated.

  4. Check Dependencies:
    If your prelaunch task involves running a script or command that relies on external dependencies, ensure that those dependencies are correctly installed and accessible.

  5. Debug Task:
    You can debug the prelaunch task by setting breakpoints in your .vscode/tasks.json file and observing its execution. This can help you identify the specific point where the task is failing.

  6. Use a Simple Task:
    If you're unsure about the exact cause of the error, consider creating a simple prelaunch task that runs a basic command (e.g., echoing a message). This can help you determine if the issue is specific to the task configuration or something else in your environment.

  7. Check Exit Code:
    If your prelaunch task is a custom script or command, make sure to check the exit code it's returning. An exit code other than 0 indicates an error. The exact error message or output may provide more insight into the problem.

  8. Update Extensions:
    Sometimes, issues can arise due to outdated or incompatible extensions. Make sure that you're using the latest version of Visual Studio Code and any related extensions.

  9. Consult Documentation:
    If you're using a specific framework or toolchain, refer to their documentation or community forums for any known issues or troubleshooting steps related to prelaunch tasks.

If you've tried the above steps and are still encountering the issue, please provide more context about your project, the specific prelaunch task configuration, and any relevant error messages you're seeing. This will help in providing more targeted assistance.
